The Augmented Zagreb Index of Trees with Given Degree Sequence

Abstract: The augmented Zagreb index of a graph is defined as the sum of over all edges of , where is the degrees of the vertex in . In this paper, we characterize the extremal trees with given degree sequence that maximize and minimize the index. Keywords: Augmented Zagreb index, Degree sequence, Tree, Extremal graph.
